• When connecting multiple devices, you must assign a unique
address to each device.
• Use cables that are 2 m or shorter in length to connect devices.
• Make sure the total length of all cables does not exceed 20 m.
• When devices are communicating, have at least two-thirds of the devices on the bus
turned on.
